BUG REPORT: Emacs is aborting sporadically by itself

[Jani Averbach]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When I was editing files (LaTeX sources, with global-font-lock t)
emacs is aborting sporadically by itself. Size of the file is about 25k.

I can't not describe any pattern for that aborting, it would happen during
editing, or when I am away from keyboard.

The emacs is compiled from cvs-source (dated:2003-03-03T13:28:38+0200).

$ ld --version
GNU ld version 2.13.2

$ gcc --version
gcc (GCC) 3.2.2

The glibc is 2.3.1


My ulimits are:
ulimit -a
core file size (blocks)  1000000
data seg size (kbytes)   unlimited
file size (blocks)       unlimited
max memory size (kbytes) unlimited
stack size (kbytes)      unlimited
cpu time (seconds)       unlimited
max user processes       2048
pipe size (512 bytes)    8
open files               1024
virtual memory (kbytes)  4194302

There is also a back trace from one of those core dumps.

Best Regards,
Jani
